Typhoon Dinah, known as Typhoon Luding in the Philippines, was the costliest tropical cyclone to form in the 1987 Pacific typhoon season. It also was the fourth typhoon to form during August 1987.[1] An area of low pressure developed near Guam on August 19, and two days later, the low reached tropical storm intensity as it moved generally west. Intensification was initially gradual, with Dinah becoming a typhoon early on August 24, before it subsequently intensified at a faster pace. Dinah reached its highest strength on August 26 before turning northward on August 28 and into a less favorable conditions aloft, which prompted weakening. Dinah entered the Sea of Japan after passing near Okinawa on August 29, where Dinah leveled off in intensity. The system then began to recurve towards southwestern Japan, and after tracking through the area, Dinah transitioned into an extratropical cyclone on August 31, although the remnants could be traced for four more days as it approached the International Date Line.
Across Okinawa, one person was killed, and six more were injured; eight homes were destroyed or seriously damaged, and 13 boats sunk or were damaged. Damage exceeded $1.3 million (1987 USD). On the island of Kyushu, 250 homes were flooded and about 450,000 homeowners lost power. Throughout Japan, eight people perished, damage totaled $604 million and 89 were wounded. The typhoon destroyed nearly 40,000 dwellings and an additional 600 were flooded. In South Korea, 4,372 structures were destroyed, leaving more than 11,000 people homeless. Nationwide, the typhoon was responsible for flooding 80,000 ha (197,685 acres) of crops. Property damage was estimated at $39.1 million.
